Patented .Nov. 24, 1 936- UNITED STATES VENETIAN BLIND Samuel Hammer,Brooklyn, N. Y assignor to United Metal Box 00., Inc., Brooklyn, N. Y.,a corporation of New York Application May 18, 1 934, Serial No. 726,223.4 Claims. '(01. 156-17),

This invention relatesto improvements in the. construction and operationof Venetian blinds.

An object of the invention is to provide, in

combinationwith the raising and lowering cords of a Venetian blind,means for hooking the bot-' tom of the blind to the window sill, or thelike,

so that a lifting pull exerted on the raising cords,

will exert a downward pull on the lowermost slat of the blind and holdthe blind taut to prevent it from flapping in the wind.

Other objects of my invention will either become apparent or bespecifically referred to in the following description thereof whereinreference is made to the accompanying drawing, in

which I Figure l is an elevational view of a preferred form of myimproved blind, as the same would appear when it is suitably mounted ona window frame.

Figure 2 shows the manner in which the hooking device, shown in thelower left-hand :corner of the blind in Figure 1, is secured to a windowsill or the like in such a way that an upward pull on the lifting cordwill exert, through the lowermost slat, a downward pull on the blind.

Figure 3 shows a modified form of the hooking device shown in Figure '2and the manner in which the same maybe secured to a window sill or thelike. i

Referring now to Figure 1,'it will be seen that my blind comprises ahead bar In mounted in any suitable manner at the-topof a window suchfor example as by supporting the ends of the bar in brackets H and I2.In the example shown, the

brackets are fastened at the upper corners of the window frame l3,having a sill [4. A slat l5 is secured to the head bar l0 by means ofany suitable supports l6 and I1, depending from the head bar, includingtrunnions l8- and I9, mounted in the ends of the slat 15, respectively.A series of other slots 2!, terminating in a lowermost slat 22, aresuspended from the tilting slat l5 by flexible members 23 made of anysuitable flexible material, but preferably fabric tapes. The tapes 23'are secured to the edges of the slats i5, 2| and 22 in any suitablemanner such for instance as by securing means cooperating with apertures24 formed in the edge faces of the slats. All of the slats and the headbar are perforated'as at 25,

I see Figure 2, to permit the passage therethrough of raising andlowering cords 26 and 21. The

ends of the cords 26 and 21 are fastened to the bottom of the lowermostslat 22 at points'28 and 29 removed from the holes 25 for reasons tohereinafter described.

Pulleys 30, 3| and 32, mounted in the head bar, are provided to positionand guide the cords 2B and 21 when they are pulled from their'verticallyspaced positions to one side of the window where they pass through alocking device 33 adapted to grip the cords and. thereby hold the blindin any desired position, such for example as that illustrated in Figure1.: Hooks 34 are slidably mount- 1 'ed on the raisingand lowering-cords26 and 21 between the point of attachment of the cords to the slat 22and the hole 25 in the slat through which the cords'passupwardly towardthe head bar. Eyes 35, with which the hooks 34 are adapted to engage,are mounted in the Window sill for reasons to be hereinafter described.

' The operation of the blind just described is similar to that of blindsof this general class ex- '-cept that the over-all bundling height ofthe slats in this case will be considerably less than it would be ifladder tapes were used, in which case the bundling height would beincreased by an amount equal to the summation of the thicknesses of theslat-supporting cross-tapes of the ladder tape.

Figure 2, showing the lower left-hand corner of Figure 1 when the blindis in fully lowered position, illustrates the manner in which the bot;tom of the blind may then be secured to the window sillor the like anddrawn taut to prevent it from flapping in the wind. One of theadvantages of this means of fastening the blind is that after the hook34 is secured to the eye 35 an upward blind-raising pull on the cord- 26will exert a downward pull on the slat 22 as indicated by the arrows.The extent to which the slat 22 may be pulled downwardly is governed bythe length of the tapes 23 upon which all the slats are hung from thetopmost slat I5.-

I illustrate in Figure 3 a modified form of hooking device comprising aneye adapted to slip on the cord 26 in a-manner similar to that of thehook 34 just described. The eye 90 is provided'with an enlarged head 9|adapted to cooperate with a slotted fixture 92 which is secured to thewindow sill in any suitable way. Itwill be the preferred embodiment ofmy invention; it is conceivable that various modifications in theconfiguration, composition and disposition of the component elementsgoing to make up my invention as a whole, as well as in the selectivecombination and application of the respective elements, may occur tothose skilled in the art, and no limitation is intended by thephraseology of the foregoing description or illustrations in theaccompanying drawing.

What is claimed is:

1. A Venetian blind comprising a series of flexibly connected slatsterminating in a lowermost slat, and flexible raising and loweringmembers extending through all said slats and connected to the bottom ofthe lowermost slat, in combination with hooking means slidably securedto said raising and lowering members at a point on said members betweenthe connection of said members to the lowermost slat and that portion ofsaid members which passes upwardly through said slat, and means forconnecting said hooking means to a fixed point below said lowermostslat, whereby 9. raising pullon said flexible members will exert adownward pull on said lowermost slat.

2. A Venetian blind comprising a series of flexibly connected slatsterminating in a lowermost slat, and flexible raising and loweringmembers extending through all said slats and connected.

said raising and lowering members at a point on said members between theconnection of said members to the lowermost slat and that portion ofsaid members which passes upwardly through said slat.

3. A Venetian'blind comprising a series of flexibly connected slatsterminating in a lowermost slat, and flexible raising and loweringmembers extending through all said slats and connected to the lowermostslat at a point spaced from that at which said flexible members passthrough said slat, in combination with means slidably connecting to afixed point below the lowermost slat that portion of said raising andlowering members disposed between their connection to said slat and thepoint at which said members pass therethrough whereby a-raising pull onsaid flexible members will exert a downward pull on said lowermost slat.

4. A Venetian blind comprising a series of flexibly connected slatsterminating in a lowermost slat, and flexible raising and loweringmembers for said slats connected to the lowermost slat, in combinationwith means slidably connecting :to a fixed point below the lowermostslat a portion of said raising and lowering members whereby a raisingpull on said flexible members will exert a downward pull on saidlowermost slat.
